MSM6222B-xx Overview
The MSM6222B-xx is a dot matrix LCD controller which is fabricated in low power CMOS silicon gate technology. Character display on the dot matrix character type LCD can be controlled in bination with a 4-bit/8-bit microcontroller. This LSI consists of 16-dot MON driver, 40-dot SEGMENT driver, display data RAM, character generator RAM, character generator ROM and control circuit.
